HOSE NOZZLE.

SPECIFICATION forming part of Letters Patent No. 378,308, dated February 21, 1888.

Application filed July 5, 1887'.

To (LIZ whom it 11mg concern.-

Be it known that I, ALBERT HALLOWELL, a citizen of the United States, residing at Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented a new and useful Improvement in Graduating Spray Hose-Nozzles, of which the following is a specification.

My invention relates to that class of hosenozzles which are capable of being made at will to deliver either a fine spray, a coarse spray, or a solid stream; and it consists in the construction and combination of parts, as hereinafter set forth.

The object of the invention is to provide a hose-nozzle of superior construction, both in respect to excellence of the result attained by its use and to the economy in the manufacture thereof.

My invention is illustrated in the accompanying drawings, in which-- Figure 1 is a central vertical section of a hose-nozzle embodying myinvention, and Fig.

2 is an elevation of the main water-tube and the valve-disk attached thereto.

' Similar reference-numbers refer to similar parts in both views.

This hose-nozzle is attached in the usual way to a piece of hose by the coupling-screw upon the base of the main water-tube 1, or in any other convenient and suitable way, the washer 2 prevent ing leakage at the junction in the usual way when the coupling that is illus trated is used. I prefer to provide the said water-tube 1 upon its exterior surface with the screw-thread 3, by which it engages with the liquid-controller it, although any other equivalent nieaus of engaging the main water'tube 1 with the liquid-controller 4 may be sometimes adopted. The main watertube l is provided with an interior water-passage, 5, leading from its base to a point near its top, and with one or more ports, 6, leading from the said central passage to the space exterior to the said tube and near the top thereof.

The liquid'controller i is preferably pro vided with a packing-nut, 7, to confine the packing S and prevent leakage of liquid at this Serial No. 243,398.

(No model) point, although a quite good result maybe attained without these. i

The liquid-controller 4 is chambered out at its upper end, in order that a liquid-passage may be formed outside the main water-tube 1. The forward end, 9, of the water-tube 1 is preferably usually reduced in diameter, in order to reduce the necessary weight of the complete device, as shown. I prefer to make a portion at least of the chambered-out part of the liquid controller 4 at the upper end thereof cylindrical, and I form upon the outer surface of the valve-dislcarrying extension 9,, just below the valve-disk 10 at the end thereof, one or more oblique wings, 11, which fit and-move in the said cylindrical passage in the end of the said liquid-controller. The wings 11 are shown as being made of portions of the threads of a doublethreaded screw, although they may be made in any suitable manner; but it is desir' able that the outer surfaces of these wings should nearly fit the interior of the cylindrical end of the liquid-controller 4, in order that when a spray is being formed the water may be guided from the end of the liquid-controller in a somewhat inclined direction. The disk 10 is shown as made nearly flat, although a valve of a conical or rounded form is sometimes used instead thereof, the smaller part of the valve being then preferably placed toward the end of the device that is attached to the hose, and the end of the liquid-controllers suitably shaped to receive the said conical or rounded valve.

Upon the delivery end of the liquid-controller is attached the delivery-nozzle 12, thereby forming a chamber surrounding the valve 10 and unobstructed except by said Valve. Said nozzle is preferably made with a contracted discharge-orifice in its end and with its interior surface decreasing in diameter gradually as the distance from the end of the liquid-controller i increases and the dischargeorifice is approached.

Sometimes the interior of the delivery-nozzle is made with straight sides, thus forming a frustum of a cone. I have found that the shape of the interior of the discharge-nozzle 12 may be very greatly changed many desirable way without rendering the working of the device less satisfactory to an injurious amount, and I do not desire to limit myself to the exact shape of deliverynozzle that is shown.

This hose-nozzle is operated by bringing the valve-disk 10 more or less closely to the end of the liquid-controller 4, which is done in the structure illustrated by revolving the latter about the main water-tube. As long as the oblique wings 11 are within or partially within the cylindrically-chambered end of the liquidcontroller 4 the liquid will issue, when the device is attached to a suitable means of supplying liquid, from the discharge-orifice in the delivery-nozzle 12 in aspray of greater or less fineness, according as the valve-disk is more or less close to the end of the liquid-controller 4, while when the main water-tube is so adjusted that the oblique wings 11 are entirely outside of and at a little distance from the end of the liquid-controller 4 the liquid will issue from the discharge-orifice in a solid stream. The flow of liquid from the nozzle may be entirely stopped by bringing the valve-disk 10 firmly in contact with the end of the liquidcontroller 4, which then forms a seat for said valve.

I prefer to make the area through all of the liquidpassages-of this device, except that between the valve-disk 10 and its seat on the end of the liquid-controller 4, as large as or larger than the discharge-orifice in the delivery-nozzle 12, in order to get an undiminished flow through said orifice when the solid stream is being delivered.

WhatI claim as new, and desire to secure by Letters Patent, is-

1. The hose-nozzle which consists of the main water-tube provided with its interior liquid-passage, the port in its side, the valve upon its forward end, and the oblique wing upon its. exterior and new to the said valve, the liquid contro'ller upon the exterior ofsaid main water-tube and having a valve-seat and achamber at its forward end, said chamber inclosing said oblique wing and said port when the valve is near said forward end of theliquidcontroller, means for adjusting the longitudinal position of said liquid-controller with respect to said main water-tube, and the deliverynozzle, with its discharge-orifice, attached to said liquid-controller, and forming therewith a chamber between said liquid-controller and said discharge-orifice, unobstructed except by said valve, which it surrounds, substantially as described, and for the purposes specified.

2. The hose-nozzle consisting of the main water-tube, with its interior liquid-passage, the port inits side, the valve upon its forward end, the oblique wing upon its exterior near to said valve, and the screw-thread upon its exterior surface, combined with the liquid-controller upon the exterior of said tube, pro vided with the screw-thread in its interior, which engages with the screw upon the exterior of said tube, the valve-seat, and the chamber at its forward end, said chamber inolosing said oblique wing and said port when said valve is near the end ofsaid liquid-controller, means for preventing the escape backward of liquid between said main water-tube and said liquid-controller, and the delivery-nozzle, with its dischargeorifice, attached to said liquidcontroller, and forming therewith a chamber between said orifice and said liquid-controller, unobstructed except by said valve, which it surrounds, and contracted toward said discharge-orifice, substantially as described, and for the purposes specified.

ALBERT HALLOWELL.
